The OFF file format is a simple text-based format capable of storing 2D and 3D geometry and was originally developed for the Geomview application. There is also an extension to the OFF format used by the Stella4D application to enable storage of four-dimensional data.

The format can contain common vector information such as vertices, faces, shape, edge information and also has support for including color information. As the format is text based the files can become rather large with no built-in compression options available.

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.

There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.
